Violence was particularly concentrated in poor inner-city neighborhoods including Roxbury, Dorchester, and Mattapan. There were 22 youths (under age 24) killed in Boston in 1987, with that figure rising to 73 in 1990. Operation Ceasefire entailed a problem-oriented policing approach, and focused on specific places that were crime hot spots. Focus was placed on two elements of the gun violence problem, including illicit gun trafficking and gang violence.
Within two years of implementing Operation Ceasefire in Boston, the number of youth homicides dropped to ten, with one handgun-related youth homicide occurring in 1999 and 2000. Youth homicides later climbed again with 37 in 2005 and reaching a peak of 52 in 2010.
The Operation Ceasefire strategy has since been replicated in other cities, including Los Angeles and Oakland, California and various cities in New Jersey including but not limited to Newark, Irvington, Camden and Paterson.
Operation Ceasefire is also the name for a guns-for-tickets exchange program that was once run by the Denver Police Department, in conjunction with the Denver Nuggets, Colorado Rockies, and Denver Broncos.
